SurfaceFlinger: Detect Rel Z loops Telemetry indicates we are sometimes seeing crashes due to infinite recursion in isHiddenByPolicy. We detect this condition (relative Z loop) and add a helpful log. The performance impact should be minimal as relative Z is rare, and the traversal isn't doing any heavy work or sp<> promotion.
